Hi,<br/><br/>When referring to a defined class in a classification system, it is corect (or incorrect) to capitalize the classification?<br/><br/>For example, when referring to a stong hurricane, is it correct to write "Class 4" or should it be "class 4"?<br/><br/>Note that the criteria for the term are rigourosly and specifically defined in the classification system.<br/><br/>Thanks in advance!
